Fundamental Properties:
Graphene transferred onto PET substrates retains its exceptional electronic, optical, and mechanical properties while offering flexibility and transparency from the PET substrate. The PMMA-assisted transfer ensures high-quality, uniform graphene films with minimal defects, making it suitable for flexible and transparent electronic applications. Key properties include: Electrical Properties: High electrical conductivity with carrier mobility exceeding 10,000 cm²/V-s. Typical sheet resistance <=500 Ω/sq (monolayer) and <=100 Ω/sq (multilayer). Low Raman D/G ratio confirms minimal defect density after PMMA-assisted wet transfer.
Optical Transparency: Graphene on PET transmits ~97.7% of visible light, ideal for transparent electronics.
Mechanical Flexibility: The combination of graphene and PET enables robust, bendable devices without compromising performance.
Thermal Properties: High thermal conductivity of graphene complements the flexibility and thermal stability of PET.

Applications:
Flexible Electronics: Graphene on PET is ideal for flexible circuits, displays, and wearable electronic devices.
Optoelectronics: Suitable for transparent conductive films in touchscreens, OLEDs, and photovoltaic devices.
Sensors: Highly sensitive for gas, chemical, and biological detection, benefiting from the lightweight and flexible PET substrate. Energy Applications: Used in flexible electrodes for supercapacitors, batteries, and other energy storage devices.
Transparent Coatings: Graphene on PET can serve as a durable and conductive layer for various industrial applications.
